Welcoming the 163 refugees, new Prime Minister Justin Trudeau said his country was "showing the world how to open our hearts".
The newly elected Liberal government has pledged to take in 25,000 refugees by the end of February.
Canada's stance on the issue differs sharply to that of the US, which has been reluctant to take in migrants.
Another plane is due in Montreal on Saturday.
Immigration Minister John McCallum said all 10 provinces in Canada are in favour of accepting the refugees.
"This is a great moment for Canada," he said. "This shows the way we really are. It truly is a non-partisan, national project."
Since early November, hundreds of Syrians have already arrived in Canada via commercial aircraft.
A total of about 300 Syrians will arrive this week.
The Toronto Star, the country's largest-circulation daily newspaper, ran a cover story on Thursday welcoming the refugees.
The US administration has said it will take in 10,000 refugees over the next year. Some Republican governors have unsuccessfully tried to keep them from coming to their states after deadly terrorist attacks in France and California.
Leading Republican presidential candidate Donald Trump said after the California attacks that all Muslims should be blocked from coming to the US, drawing condemnation across the globe.
Global News reporter Mike Armstrong has been taking photos of refugees at Canada's refugee processing centre in Amman, Jordan.
Some families have been told they may move in weeks, he tweeted.
About 800 refugees are going through screening tests in Lebanon and Jordan daily, Mr McCallum said.
Mr Trudeau, who swept the 19 October Canadian elections, has a different stance on refugees from that of his predecessor, the conservative Stephen Harper, who did not wish to resettle more people.
Unaccompanied men will be excluded from the resettlement programme but officials said this had nothing to do with national security concerns.
"We want them to have a roof over their head, and the right support," said Mr McCallum.
"It takes a bit of time to put that all in place. We're happy to take a little more time than originally planned to bring our new friends into the country."
Those who will be considered refugees include families, women deemed to be at risk, and gay men and women.
The first military plane carrying Syrian refugees to be resettled in Canada has arrived in the country.

This is the first time inflation has fallen below 9% in almost two years.
Despite the fall, analysts said the central bank was unlikely to cut interest rates, which currently stand at 8.5%, next week.
India's central bank has increased rates 13 times since March 2010 in an effort to hold down rising prices.
"The headline inflation has come down because of food inflation easing, but the manufacturing momentum is strong," said Sonal Varma at Nomura in Mumbai.
"From the [the central bank's] perspective, core inflation is still elevated, and so we are not expecting any rate move on 24 January," she said.
However, analysts do expect rates to come down in the coming months after Indian Finance Minister Pranab Mukherjee said recently that policymakers would start concentrating on improving economic growth rather than taming inflation.
India's inflation rate fell sharply in December to 7.5% from 9.1% in the previous month, partly due to an easing in the rate of food price rises.

Those detained are believed to have come from China's Xinjiang region with ties to the attacker, Anadolu says.
Deputy PM Veysi Kaynak also said they were closing in on the gunman, who he said was possibly an ethnic Uighur.
Also on Thursday, there was an explosion near the courthouse in the city of Izmir in western Turkey.
Social media images showed two cars ablaze and several people were reported wounded.
Other images showed what appeared to be the body of a man carrying a gun, amid media reports he was an attacker who was shot dead by police.
Anadolu reported a second man was shot dead and police were seeking a third.
So-called Islamic State (IS) says it carried out the Istanbul attack over Turkey's military involvement in the Syrian civil war.
The authorities have reportedly tightened security at Turkey's land borders and airports to prevent the attacker from fleeing the country.
Turkish media have run images of a suspect, saying the pictures were handed out by the police. But the police have given no official details.
The Turkish foreign minister has said the authorities have identified the attacker, but has not given further details.
Special forces made the early morning arrests at a housing complex in Selimpasa, a coastal town on the outskirts of Istanbul, after police were reportedly tipped off that individuals linked to the attacker were in the area.
Uighurs were among those arrested - the number was not confirmed - on suspicion of "aiding and abetting" the gunman, Anadolu reported.
At least 36 people were already in custody over suspected links to the attack, many of whom were picked up in an earlier police operation in Izmir.
Several families had recently travelled there from Konya, a central city where the main suspect was said to have stayed for several weeks before the attack.
The Uighurs are a Turkic ethnic group who are mainly Muslims, primarily living in the Xinjiang Uighur Autonomous Region in China. Their language is related to Turkish and a substantial Uighur diaspora lives in Turkey.
Some Uighurs have complained for years about persecution at the hands of the Chinese authorities. Al-Qaeda has long-developed links with Uighur jihadists - known as the Turkestan Islamic Party (TIP) - and has offered them military training in Afghanistan.
Uighur jihadists appear to have joined the fighting in Syria in relatively large numbers, alongside both Jabhat Fateh al-Sham (JFS, formerly al-Qaeda's Syrian branch al-Nusra) and al-Qaeda's rivals, the so-called Islamic State (IS).
They have featured prominently in IS propaganda.
It is believed Uighurs make their way to Kyrgyzstan through the mountains between Kyrgyzstan and Xinjiang. Once in Kyrgyzstan, they fly to Turkey using forged Kyrgyz passports.
Separately, Mr Kaynak told Turkish broadcaster A Hamer that the authorities knew where the suspect, who he described as "specially trained", was hiding, without giving further details.
He confirmed the gunman had acted alone, but may have had help inside the nightclub.
Witnesses to the new year attack said more than 100 rounds of bullets were fired which, the BBC's security correspondent Frank Gardener says, indicates the gunman had at least some rudimentary military training.
Mr Kaynak expressed confidence in the Turkish police operation but said he could not rule out the possibility of the attacker fleeing the country.
Previous media reports incorrectly suggested the culprit was a national from Kyrgyzstan, after a passport photo claiming to show the attacker was circulated.
It later emerged the passport belonged to someone unrelated to the attack.
Kyrgyzstan's embassy in Turkey has since asked the media to retract the reports and issue an apology.
More than half of those killed in Sunday's attack on Istanbul's popular Reina nightclub were foreigners, including citizens from Lebanon, Saudi Arabia, Israel, Iraq and Morocco.
The gunman managed to escape in the aftermath of the attack.
A day later, IS issued a statement saying "a heroic soldier" belonging to the group had carried out the attack in retaliation for Turkey's military role in northern Syria.
Mr Kaynak also said on Thursday Turks were questioning the use of the country's Incirlik air base by both Nato and the US-led coalition launching air strikes on IS in Syria and Iraq.
Turkey launched a military operation in Syria in August to push back IS and Kurdish forces.
Some of Turkey's big cities have since been targeted in a number of bomb attacks by IS and by Kurdish militants.

Turkey has arrested a number of people of Uighur ethnicity over a deadly nightclub attack that killed 39, the state-run news agency reports.
